Detailed Description

FMC bypass jumper J19 must be connected between pins 1-2 (bypass) to enable JTAG access to the FPGA on the basic SP605 board (without FMC expansion modules installed), as shown in Figure 1-7. When the VITA 57.1 FMC LPC expansion connector is populated with an expansion module that has a JTAG chain, jumper J19 must be set to connect pins 2-3 in order to include the FMC expansion module's JTAG chain in the main SP605 JTAG chain.

The JTAG chain can be used to program the FPGA and access the FPGA for hardware and software debug.

The JTAG connector (USB Mini-B J4) allows a host computer to download bitstreams to the FPGA using the Xilinx iMPACT software tool. In addition, the JTAG connector allows debug tools such as the ChipScope® Pro Analyzer tool or a software debugger to access the FPGA. The iMPACT software tool can also program the BPI flash via the USB J4 connection. iMPACT can download a temporary design to the FPGA through the JTAG. This provides a connection within the FPGA from the FPGAs JTAG port to the FPGAs BPI interface. Through the connection made by the temporary design in the FPGA, iMPACT can indirectly program the BPI flash from the JTAG USB J4 connector. For an overview on configuring the FPGA, see “Configuration Options,” page 55.

7. Clock Generation

There are three clock sources available on the SP605.

Oscillator (Differential)

The SP605 has one 2.5V LVDS differential 200 MHz oscillator (U6) soldered onto the board and wired to an FPGA global clock input.

•Crystal oscillator: Epson EG-2121CA-200.0000M-LHPA

•PPM frequency jitter: 50 ppm
